Sash-fastener



THO. W, H. MOSELEY, OF COLUMBUS, OHIO.

SASHjFASTENER.

Specification of Letters Patent No. 5,549, dated May 2, 1848.

T 0 all whom it may concern Be it known that I, Trios. W. H. MosnLnr, ofColumbus7 county of Franklin, and State of Ohio, have invented a new anduseful Improvement on Machines to Hold Up and Down lVindow-Sashes whenin a lVindow; and I do hereby declare that the following is a full7clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making part of thisspecifica-tion.

The nat-ure of my invention consists in having a peculiar, heavy end toa lock to hold up and down sashes in a window. This peculiarity in alock for this purpose generally prevents it from turning over when thewindow sash is hoisted or lowered. And in addition to this, that thelock may without fail keep its position while the sash is in motion Ihave introduced a spring which is attached to the lock and operates withit.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I make the lock, of iron, brass, or other strong metal, varying in sizegenerally from one fourth to half inch thick and from one to two inchesin diameter. The spring is made of brass, or steel. It is about threeand a half inches long, and about one third of an inch wide and thinenough to Ayield conveniently to the touch of the thumb.

Figure l is the detached top view of t-he holder or lock. 2 is thedetached spring; 8 the underside view with the spring attached. et isthe end edge view with the spring attached. 5 is the top view with thespring attached. A, Fig. 1 is a hole in the lock, making its fulcrum,through which passes a screw fastening the lock to the sash. This holeis above the center of the circle of the machine therefore making themachine a cam or eccentric. B is the edge, which goes next the side ofthe window when you hoist the sash; and C t-he edge which goes next theside of the window when you let down the sash. The C end is heavier thanthe B end, like other machines in use for a similar purpose.

d and h are two elevations on the top of the lock see Figs. 5 and 6.These elevations are to come in Contact with the upper end of the springK each one at its proper time and place. The spring passes up and downthe sash over the top of the machine with a hole near its upper end at,Z, Fig. 2 through which hole passes the fulerum screw of the lockconnecting the spring to the lock. The spring extends far enough abovethe upper edge of the lock to allow the two elevations (Z- and -ztostrike against it. The spring also has another hole at its lower endwhich admits a screw to hold it from playing to the right or left. Mymachine is a self adjusting sash lock, to hold up and down window sasheswhen in a window at any given point, which can not turn over one way orthe other unless you desire it. This is done by having my lock soconstructed as to have the center of gravity from live to twenty degreesbelow the horizontal line of the fulerum of the lock in its heavy end;this gives so much weight below the line of the fulcrum, that anyordinary interferance at the side of the window will not turn the lockover as you move the sash up. Besides this, I have an additional safeguard to prevent the lock turning, particularly when the sash is letdown. This latter is a spring Fig. 2 in the drawing. It will be seen inFig. 5 that the elevation d will strike the upper end of the spring ateand prevent the lock turning over should it attempt to do so, as thesash is being hoisted and so will the elevation -L- in Fig. 6 strike thespring at z' and prevent the lock turning back should it attempt to doso as the sash is let down. Thus it will be seen that the window isalways secure from falling or being hoisted Without further assistanceto the lock save to turn it under the spring before hoisting or loweringthe sash.

I/Vhen you desire to turn the lock for the purpose of hoisting orlowering the sash, you have but to press the spring in the neighborhoodof K with the thumb and tip the end of the lock with a linger of thesame hand, and from the pressure upon the spring its upper end riseswhich admits the free passage of the elevations el, and h, under it.

What I claim as my invention and desire to secure by Letters Patent inthe within described sash fastener, is-

l. Having two eccentric sides similar to each otherwthe onepreponderating over the other and hung upon a pin, so that in oneposition the sash will be held up, by the pressure of one side of thefastener against the casing of the window; and in the reverse positionit will be held down by a similar preeeme of the other. side of thestructed and operating substantially as defastner, tne prepondoratingside Causing scribed.
